CASEMENT-HOLDER.

Specification of Letters Patent.

Patented Nov. 29, 1921.

Application filed September 18, 1919. Serial No. 324,376.

To all whom it may concern Be it known that I, WALTER L. BURTIS, a citizen of the United States, and a resident of the city of Tuckahoe, in the county of W'Vestchester and State of New York, have invented a new and Improved Casement- Holder, of which the following is a full, clear, and exact description.

This invention relates to improvements in,

A further object is to provide a device of the character stated which will be of simple inexpensive construction, neat in appearance and strong and durable in use.

With these and other objects in view, the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim. V

In the accompanying drawings:

Figure 1 is a view in elevation illustrating my improvements.

Fig. 2 is an enlarged fragmentary view 111 horizontal section.

Fig. 3 is a view in section on the line 3-3 of Fig. 2.

Fig. 4 is a view in section on the line 4-4 of Fig. 3.

1 represents a window frame and 2 a window having hinged connection?) at one edge with the upright member 4.- of the frame.

A bracket 5 is secured to the inner face of the window 2 adjacent its hinged edge and a curved bar 6 is made integral with, or otherwise fixed to the bracket 5. The bar 6 has its upper and lower faces toothed or serrated, as shown at 7 and is movable through a slot 8 in a plate 9 fixed to the frame member bar 4, said bar being recessed as shown to accommodate the bar 6.

A cam 10 has rotary mounting on a rivet 11 secured to plate 9 and is provided with a finger hold 12 to facilitate its movement.

A lug 13 on the bar 6 limits its movement through the plate 9 and hence limits the opening movement of the window.

The operation is as follows:

When the window is positioned as desired, either closed, opened, or partially opened, the cam 10 is turned so as to engage the upper serrations 7 of the bar 6 and at the same time force the lower serrations 7 into engagement with the lower wall of slot 8, thereby effectually locking the parts against moving and securing the window in the position desired.

Various slight changes might be made in the general form of the parts described without departing from my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claim.

I claim:

The combination with a frame having an opening therein and a hinged window connected to the frame, of a plate located inside the window positioned over said opening and having a slot therein registering with the opening, the window and movable through said slot and opening, said bar including serrated upper and lower faces, a beveled edge cam pivotally connected to and movable over the face of the plate, an operating handle on said cam for operating the same, said cam adapted to be moved into locked engagement with one serrated face of the bar and to force the other serrated face into positive locked engagement with the wall of the slot in the plate, whereby said bar may be positively locked to hold the window in any position of adjustment.
